Attempting to export obj+mtl+jpg file into different program

[NorrelleWalker]

Hello! I am attempting to export my saved SH3D project into the Spoke program on mozilla hubs to use a customer scene. I loosely understand that the .obj file only contains geometry info, and the .mtl & .jpg files are for color and texture, but how do I combine these?

How do I combine the obj+mtl+jpg file into a single file that I can import as a 3D space? Would I need to download Blender or another program to combine these files, then export the merged file from there? [:-?]

Finally, I would need to convert the file to a .glb scene to be able to use it in Mozilla Hubs. I have been able to successfully import the .obj file only as a 3d model, but of course the textures nd colors are missing. Any help or insight would be greatly appreciated! Thank you! [:)>-]

Many formats like Collada / DAE and 3DS combine shapes and their colors in one file, but generally texture images are stored in separated files.
About GLB format see this thread.
